SHA1(3) 1 SHA1(3)sha1 - Calculate the sha1 hash of a stringSYNOPSIS
string sha1 (string $str, [bool $raw_output = false])
DESCRIPTION
Calculates the sha1 hash of $str using the US Secure Hash Algorithm 1.
PARAMETERS
o $str
- The input string.
o $raw_output
- If the optional $raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20,
otherwise the returned value is a 40-character hexadecimal number.
RETURN VALUES
Returns the sha1 hash as a string.
EXAMPLES
Example #1
A sha1(3) example
<?php
$str = 'apple';
if (sha1($str) === 'd0be2dc421be4fcd0172e5afceea3970e2f3d940') {
echo "Would you like a green or red apple?";
}
?>
NOTES
Note
Secure password hashing
It is not recommended to use this function to secure passwords, due to the fast nature of this hashing algorithm. See here for
details.

HASH_FINAL(3) 1 HASH_FINAL(3)hash_final - Finalize an incremental hash and return resulting digestSYNOPSIS
string hash_final (resource $context, [bool $raw_output = false])
DESCRIPTION PARAMETERS
o $context
- Hashing context returned by hash_init(3).
o $raw_output
- When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits.
RETURN VALUES
Returns a string containing the calculated message digest as lowercase hexits unless $raw_output is set to true in which case the raw
binary representation of the message digest is returned.
EXAMPLES
Example #1
hash_final(3) example
<?php
$ctx = hash_init('sha1');
hash_update($ctx, 'The quick brown fox jumped over the lazy dog.');
echo hash_final($ctx);
?>
